Invision Community 4: SEO, prepare for v5 and dormant account notifications Matt November 11, 2024Nov 11
Posted October 25, 200618 yr I know enabling GZIP compression saves on bandwidth, but how does it affect server load (ie. CPU and RAM) ?
October 25, 200618 yr If gzip is used, the server has to compress the files, so technically it does use a bit of server load. However, unless you set the compression level to like 9, it should be fine.

October 26, 200618 yr How do you change the compression?It's a setting in the admin area, in the same spot as "Use compression?."
October 26, 200618 yr How do you change the compression?http://us3.php.net/manual/en/function.ob-gzhandler.phpob_gzhandler compression level use zlib.output_compression_level, which is -1 per default, level 6. To change the compression level on the fly, simply use ini_set: <?php ini_set('zlib.output_compression_level', 1); ob_start('ob_gzhandler'); echo 'This is compressed at level 1'; ?>Note that I haven't really played around with this much - I've set compression level in scripts when using zlib.output_compression, but not ob_gzhandler. It's safer to just leave it on the server default usually.
